BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidensplant, botanically known as Bidens triplinervia and hereinafter referredto by the name ‘Haflrest’.

The new Bidens plant is a product of a planned breeding programconducted by the Inventor in Okayama-ken, Japan. The objective of thebreeding program is to create new freely-branching Bidens plants withunique ray floret coloration.

The new Bidens plant originated from a self-pollination made by theInventor in Okayama-ken, Japan in January, 2010 of Bidens triplinervia‘K-SAIKA001’, not patented. The new Bidens plant was discovered andselected by the Inventor as a single flowering plant from within theprogeny of the stated self-pollination in a controlled greenhouseenvironment in Okayama-ken, Japan in May, 2010.

Asexual reproduction of the new Bidens plant by vegetative cuttings in acontrolled environment in Okayama-ken, Japan since June, 2010 has shownthat the unique features of this new Bidens plant are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Bidens have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity, without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Haflrest’. These characteristics incombination distinguish ‘Haflrest’ as a new and distinct Bidens plant:

-   -   1. Upright, outwardly spreading to somewhat trailing and        mounding plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Freely flowering habit.    -   5. Long flowering period.    -   6. Large inflorescences with dark orange-colored ray florets        with yellow-colored borders and bright yellow-colored disc        florets.    -   7. Strong peduncles that hold the inflorescences above and        beyond the foliar plane.

Plants of the new Bidens differ primarily from plants of the parent,‘K-SAIKA001’ in ray floret color as inflorescences of ‘K-SAIKA001’ haveyellow and subdued orange bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidenstriplinervia ‘Haflpare’, disclosed in a U.S. Plant Patent applicationfiled concurrently. In side-by-side comparisons conducted inOkayama-ken, Japan, plants of the new Bidens differed from plants of‘Haflpare’ in ray floret color as plants of ‘Haflpare’ have deep orangeand yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidenstriplinervia ‘Hafltibr’, disclosed in a U.S. Plant Patent applicationfiled concurrently. In side-by-side comparisons conducted inOkayama-ken, Japan, plants of the new Bidens differed from plants of‘Hafltibr’ in plant size and ray floret color as plants of ‘Hafltibr’are more compact than plants of the new Bidens and have orange-coloredray florets with orange red-colored central and lateral stripes.

Plants of the new Bidens can be compared to plants of Bidenstriplinervia ‘Hafltifrpu’, disclosed in a U.S. Plant Patent applicationfiled concurrently. In side-by-side comparisons conducted inOkayama-ken, Japan, plants of the new Bidens differed from plants of‘Hafltifrpu’ in plant size and ray floret color as plants of‘Hafltifrpu’ are more compact than plants of the new Bidens and haveorange and yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidenstriplinervia ‘Hafltufr’, disclosed in a U.S. Plant Patent applicationfiled concurrently. In side-by-side comparisons conducted inOkayama-ken, Japan, plants of the new Bidens differed from plants of‘Hafltufr’ in ray floret color as plants of ‘Hafltufr’ have ray floretswith dark orange-colored centers and yellow to light yellow-coloredapices.

Plants of the new Bidens can also be compared to plants of Bidenstriplinervia ‘Florbikano’, disclosed in U.S. Plant Pat. No. 25,087. Inside-by-side comparisons conducted in Okayama-ken, Japan, plants of thenew Bidens differed from plants of ‘Florbikano’ in the followingcharacteristics:

-   -   1. Plants of the new Bidens were taller than plants of        ‘Florbikano’.    -   2. Plants of the new Bidens had longer and thicker lateral        branches than plants of ‘Florbikano’.    -   3. Plants of the new Bidens had slightly larger leaves than        plants of ‘Florbikano’.    -   4. Plants of the new Bidens had larger inflorescences than        plants of ‘Florbikano’.    -   5. Plants of the new Bidens and ‘Florbikano’ differed in ray        floret color as plants of ‘Florbikano’ had yellow orange and        dark orange bi-colored ray florets.    -   6. Plants of the new Bidens had longer and thicker peduncles        than plants of ‘Florbikano’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Bidens plant showing the colors as true as it is reasonably possibleto obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Bidens plant.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown in 15-cm containers during October ina polyethylene-covered greenhouse in Cartago, Costa Rica and undercultural practices which approximate those generally used in commercialBidens production. During the production of the plants, day temperaturesaveraged 26° C., night temperatures averaged 18° C. and light levelsranged from 12 to 15 moles per day. Plants were pinched two times andwere 21 weeks old when the photograph and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
